Pros
This was time when they have head office in historical baroque building on small side street, 500 meters from both Kremlin, Red Square, and Cathedral of Christ the Saviour. Historically first Gold Cisco partner in Russia, and at that time Cisco seemed to be visionary, not just one of network companies. The president of the company (foreighner with very good understanding of Russia) walked through the office and shaked hands with employees, asking "how are you, how's business"? Very homy annual meetings at noble restaurant (more like family celebration than business meetings).
Cons
Companies grow, things often change. Bigger company, new (more comfortable) office, still near the City Center though now longer way from old historical lanes and city sights. More aggressive new customer acquisition & new staff acquisition means some steps back in terms of quality of projects, business processes, and step back in new staff level, people education and culture. Still good, comparing to what you can find in Moscow, but clearly not good like it was.
